Electronically limited top speed is the speed at which a computerized governor prevents a vehicle from going any faster.
This provision in a vehicle’s engine management computer prevents the driver from exceeding a preset speed, typically by deactivating the spark or fuel injectors. Presumably, the electronic limiter holds the vehicle below speeds at which it’s likely to become unstable or be damaged — one that far exceeds this country’s legal limits. In some instances, stating a vehicle’s electronically limited top speed, as opposed to just plain top speed, is a manufacturer’s way of suggesting that higher speeds are available to anyone who cares to monkey with the electronic control unit, which usually voids the warranty.
